Effective Locking Device is characterized by which statement?

• A. A padlock that any employee can unlock.
• B. A switch padlock that is vandal and tamper resistant, and can be unlocked only by the class, group or craft of employees that applied it.
• C. A device that locks automatically in bad weather.
• D. A padlock that can be opened by supervisors.

Answer: (B)

An effective locking device is designed to keep energy isolated and under the control of the worker who applied it, preventing others from removing or bypassing it. The best statement describes a switch padlock that is vandal and tamper resistant and can be unlocked only by the class, group, or craft of employees that applied it. This ensures that only the workers who set the lock can remove it, cutting off the possibility of accidental or unauthorized re-energizing and maintaining a safe environment while work is being performed. The other scenarios don’t provide the same level of protection: a padlock that anyone can unlock would allow others to remove the lock and re-energize equipment; a device that locks automatically in bad weather doesn’t address who controls the lock or the safety of the shutdown; a padlock that can be opened by supervisors bypasses the intended control by the workers performing the task.
